What Factors Affect the Market Price of Rock Nuts? 4 Factors Are of Utmost Importance

2025-02-28

Why Should We Pay Attention to the Market Price of Rock Nuts?Although mining projects require rock nuts that are of the most reliable quality and safety, due to the fact that the manufacturing technology of rock nuts is already very mature and there are numerous related manufacturers globally with varying prices, it is entirely necessary for the procurement departments of mining areas to carefully select suppliers of nuts that are inexpensive yet of reliable quality.

In addition, the purchasers in mining areas need to control project costs and optimize budget preparation through price analysis, and ultimately select suppliers with high cost performance to reduce costs. Moreover, manufacturing enterprises can also adjust their pricing strategies and optimize production processes based on price fluctuations to maximize decision-making benefits in the competition.

What Factors Affect the Market Price of Rock Nuts? 5 Factors Are of Utmost Importance. In descending order of influence, they are: raw material costs, production processes, specifications and dimensions, brand factors, market supply and demand, and other factors.

1. What Factors Affect the Market Price of Rock Nuts? The Raw Material Factor Has the Greatest Impact

What factors affect the market price of rock nuts? Rock nuts made of 40Cr, 35CrMo, stainless steel 304, and 316 are relatively expensive in price.

This is because these steel materials have high strength and their prices are significantly higher than those of ordinary carbon steel materials. If materials like [others] are used, due to their superior corrosion resistance, the cost and price are also relatively high. In addition, fluctuations in raw material prices are also affected by global industrial chains and trade wars.

For example, in 2025, the United States imposed taxes on aluminum frames and steel from Canada and Mexico, which also led to increased costs for rock nut manufacturers in the United States. Ultimately, this will cause the market price of rock nuts to rise.

Some relevant data on the prices of rock nut raw materials:

The United States: According to data from the American Iron and Steel Institute, steel prices in the United States have fluctuated significantly in recent years. For example, during 2021 - 2022, the price of medium and heavy plates in the United States rose from approximately $600 per ton to over $1000 per ton, driving the price trend of 40Cr and 35CrMo alloy steels.

Europe: According to statistics from the European Steel Association, the prices of some alloy steels in 2024 increased by about 5% - 10% compared to 2023. It is expected that in 2025, due to the trade war between the United States and Europe, steel prices will still be under upward pressure due to tariffs.

Asia: Taking the Chinese and Japanese markets as examples, on February 21, 2025, the morning quotations for 304 cold-rolled steel in the Foshan market in China generally increased by $4 - $7 per ton. In the Japanese market, the price of 304 stainless steel increased by about 3% - 5% during the same period last year.

2. The Production Process of Rock Nuts

Although the cold heading process has high production efficiency and high material utilization rate, it is generally not very suitable for manufacturing rock nuts.

The hot forging process is suitable for producing large-sized rock nuts. Although it has low efficiency and high cost, the price will also be relatively high. For commonly used steel materials such as 40Cr and 35CrMo, they need to be heated to about 1000 - 1200°C, and this heating process takes a certain amount of time, which leads to an increase in manufacturing costs.

In addition, if rock nuts require knurling and polishing processes to improve corrosion resistance, the production cost will increase, resulting in a price increase.

3. The Specification and Dimension Factors of Rock Nuts

Undoubtedly, if the produced nuts have a large diameter and thickness, they require more materials and are more difficult to produce, and thus the price will be higher.

In addition, the manufacturing of rock nuts with special specifications will have a higher price because of the small production batch and high mold cost.

Under special engineering requirements, special specification rock nuts with higher prices will be used.

Large-scale hydropower projects: For the anchoring of dam foundations and the support of underground power plants, rock nuts with higher bearing capacity are required. For example, a large number of high-strength and large-specification special rock nuts were used in the underground power plant support of the Three Gorges Hydropower Station.

Bridge projects: For bridges spanning canyons and mountainous areas, the foundation of bridge piers and slope anchoring require special specification rock nuts.

Nuclear power projects: The anchoring of the foundations and slopes of nuclear power plants must ensure safety. Rock nuts with higher seismic and fatigue resistance performance will be used in rock anchoring.

4. The Surface Treatment of Rock Nuts

In order to improve the corrosion resistance of rock nuts, rock nuts may undergo surface treatments such as galvanization, chroming, and nickel plating. The increased cost depends on the materials used. The use of expensive raw material metals will result in a higher price. For example, the price of hot-dip galvanized nuts is higher than that of electro-galvanized nuts.

In addition, due to the EU's requirements for the environmental protection performance of products, some rock nuts may need to adopt environmentally friendly surface treatment processes, which are more costly.
